Hello!

So I noticed that when opening the stitched TIFF panorama in Photoshop for touchups there would often be banding present. I have just found out that switching to Lab colourspace fixes that issue.

My question is does hugin output in LAB colourspace, or is it the XYZ - which is afaik similar and just interpreted correctly by photosghop but not declared in the file and therefore not automatically selected?

I don't know how Photoshop handles colorspaces. I haven't used it in more than 10 years!

I've always used LAB because ages ago I read somewhere that it is (technically at least) the most accurate or correct colorspace.

Only switching the colorspace should not change the appearance of an image. But it can influence the following processing.

Hugin outputs RGB images (and it keeps existing color profiles)
